摘要： The present invention relates to a fatty liver and liver fibrosis evaluation system based on impedance. The fatty liver and liver fibrosis evaluation system based on impedance provided in one aspect of the present invention uses 3-dimensional liver microtissues so that the fatty liver formation and the stiffness changes resulted from liver fibrosis induced by a test drug can be analyzed with non-invasive and highly reproducible manner.

摘要： The present invention relates to an anti-inflammatory composition comprising Epimedium koreanum Nakai, Polygala tenuifolia Willd, and Polyporus umbellatus Fries extracts or a mixture thereof as an active ingredient. The extracts and mixture prepared according to the present invention exhibit a high inhibitory effect against nitric oxide and a suppressive effect against the expression of iNOS and COX2 and thus can be advantageously used as an anti-inflammatory composition.

摘要： A microfabricated platform for mimicking the liver zonation and an evaluating method of zone-specific hepatotoxicity using the same is provided. The microfabricated platform for mimicking the liver zonation prepared according to the method of the present invention is divided into three zones of zone 1, zone 2 and zone 3 similarly to in vivo liver tissue and thus the zone-specific hepatotoxicity of a drug in the liver can be evaluated using the same. According to the present invention, the zone-specific hepatotoxicity results can be analyzed quantitatively by using image analysis, so that the platform of the present invention can be effectively used for in vitro screening of zone-specific hepatotoxicity.
